I've never pretended that I am an expert when it comes to coffee and espresso. Indeed, I've never called myself anything more than an "experienced newbie." But let me return, for a moment to the world of wine (something that I do know a little about).
One of the things I would always tell my students is that every winery in California (indeed the world, but let's keep focused) "does the same thing, but they do it differently." We all crush grapes, ferment the juice, age it for a particular length of time, and stick it in a bottle. But at each and every step, there are a number of different ways, options, that a winemaker can take, the result being that two winemakers can get the same grapes picked from the same vineyard on the same day and at the same level of ripeness . . . and yet still make radically different wines, both of which are outstanding . . . or, the differences between the two finished wines may be quite subtle, yet distinct, and still be outstanding, each in its own right. (Of course, each wine may also be $#! -- the vinous equivalent of a "sink shot," but let's not go there.)
The short answer is that there is more than one way to skin the proverbial cat: updose or down; finer grind or more coarse; heavy tamp or light; flat burr set or conical (or a hybrid) -- the options go on and on, and just like "DB or HX," both can produce great shots . . . but
different!
